6. Enrolling to Expander Module

1. Remove the wireless fire base to access the PCB with the batteries compartment. If the device is not new,

perform reset as described in item 7.

2. Enter in programming mode of the Natron expander module. Select ADD DEVICE menu and press ENTER

button. A list with already enrolled devices is shown on the screen with an order number and type of the device.

3. Scroll down to find a free address to enroll the sounder. Every free address is labeled as EMPTY.

4. Press ENTER button. Message SEARCHING >>> (arrows are blinking) appears on the screen showing that

the module is scanning for signals from a wireless device in its covering range.

Note: If there is no signal from the device in 2-minute period, the expander module will exit automatically the

programming mode.

5. Power on the sounder. If the device is new just remove the protective folio from the batteries – the

enrolling process starts automatically. If the device is powered and reset - single press the ENROLL

button. The operation LED (item 4, position 3) starts flashing in red.

6. In case of successful enrolment, the operation LED flashes 3 times in green and message DONE appears for a

while on the screen of the module. The sounder is added to the list as WSS type.

7. Test the signal strength between the sounder and the expander module. Single press the ENROLL button and

wait for the operation LED indication:

- 3 flashes in green – excellent signal strength;

- 3 flashes in orange – good signal strength, but, if possible, change the place of installation;

- 3 flashes in red – poor signal strength and it is obligatory to change the place of installation.

You can also check the signal quality for the device in DEVICE RSSI menu of the module - item 8.

8. If the signal quality and strength are excellent or good, you can proceed with mounting.

9. Use appropriate fixing elements to mount the wireless fire base to the place of installation. Follow the

instructions in item 3 to lock the sounder to the fire base if this is needed.

10. Place the sounder in the base as observe the two short marks to coincide. Move the sounder’s body up to

hide the marks. Rotate the sounder on clock side until a click is heard.

7. Reset of the Sounder

If the sounder is not new, you have to reset it before enrolment to the expander module. Check the batteries

condition. It is recommended to change all of them with a brand new.

To reset the Natron WSS, power it on with the batteries and after that press and hold ENROLL button for 5-7

seconds. The reset is complete when the operation LED flashes 3 times in green, followed from 1 long flash in

red and 1 long flash in green. Next pressing of ENROLL button will start the enrolment procedure to expander

module.

8. Checking the Signal Quality (RSSI)

The quality of the signal between the sounder and the expander module is checked at DEVICE RSSI menu of the

module. The signal quality is assessed in [dB].

1. Enter in programming mode of the module. Scroll to menu DEVICE RSSI and press ENTER button. A list with

present enrolled devices is shown on the screen with an order number and type of the device.

2. Find in the list the sounder number.

3. Press ENTER button. Refer to the table below to read the signal quality on the screen:

Signal quality

Level RSSI

Description

< -90 dB

Loss

Bad signal or no connection.

-90 ÷ -70 dB

Good

The signal is satisfactory but needs improvement. It is recommended to change the

installation place of the device.

> -70 dB

Excellent

Excellent signal.

4. You can exit the menu at any time with pressing CANCEL button.

9. Finding the Sounder Installation Place and Test

This is a procedure that helps the engineer to find the exact location of every wireless device in the fire

installation and test the connection with module.

1. Enter in programming mode of the module. Scroll to menu FIND DEVICE and press ENTER button. A list with

present enrolled devices is shown on the screen with an order number and type of the device.

2. Find in the list the sounder number which you want to locate in the fire installation.

3. Press ENTER button. Message FINDING >>> (arrows are blinking) appears on the screen showing that the

module is scanning for signals from the selected wireless device. The message will change for a while to

FINDING DONE in case of success.

4. The sounder will respond with active strobe and short sound signals.

5. The module will exit automatically the finding procedure after 70-80 seconds. You can also stop the procedure

at any time with pressing CANCEL button.

10. Replacing Batteries

It is recommended to change the batteries after 8 years of operation regardless of their indicated discharge level.

Always use only batteries approved by the manufacturer - Panasonic CR123A 3V or other with similar

characteristics. Attention: After indication from the panel/expander module for low battery of a device, the user/

installer must replace the discharged batteries with new within one month. The remaining shelf time of the new

batteries must not be less than 6 years.

1. Disable the sounder operation to avoid fault messages.

2. Disassemble the sounder as described in item 3.

3. Remove the old batteries and place the new as observe the +/- polarity.

4. Assemble the sounder back in place.

5. Enable the sounder operation.

6. Check the signal quality in DEVICE RSSI menu of the expander module.

7. Test the sounder operability.

CAUTION: Do not expose used batteries to fire, hot ovens, or mechanical crushing/cutting as this can result in an explosion.

Exposing batteries to extremely high environmental temperatures or low air pressure can result in explosion or the leakage of

flammable liquid or gas.

DISPOSAL: Follow local regulations regarding disposal of the batteries.
